Specification of Letters Patent.

Patented April 17, 1906.

Application filed August 18,1905. Serial No. 274,788.

1'0 all w/wm it may concern:

Be it known that I, GEORGE MARTIN SMITH, a citizen of the United States, residing at Ivanhoe, in the county of Pitkin and State of Colorado, have invented certain new and use ful Improvements in Axles, of which the following is a specification.

This invention relates to vehicles, and more particularly to an improved form of axle for same.

The object of the invention is to provide a device of the character mentioned which can be readily attached to any farmwagon, which will be effective in operation, and which is so simple in construction as to be manufactured at a comparatively small cost.

With these objects in view the invention consis, essentially, in a peculiarly constructed axle fitting within a suitable housing and provided with an opening by means of which it is pivotally mounted upon the king-bolt.

For a full description of the invention and the merits thereof and also to acquire a knowledge of the details of construction of the means for effecting the result reference is to be had to the following description and accompanying drawings, in which Figure 1 is a perspective view of the invention. Fig. 2 is a horizontal sectional view. Fig. 3 is a longitudinal vertical sectional view. the various parts.

Corresponding and like parts are referred to in the following description and indicated in all the views of the drawings by the same reference characters.

The numeral 1 designates the axletree, the body of which is shown as rectangular in cross-section and fits within a corresponding groove 2 on the lower side of the housing 3. The opposite ends of the axletree 1 are rounded and tapered to form spindles 4. Washers 5 are placed upon the inner ends of the spindle and bear against shoulders 6, formed by flaring the sides of the rectangular portion of the axletree outwardly at the opposite ends thereof. It will be observed that the axletree 1 is broadened out and laterally enlarged at an intermediate point 7 and provided with an opening 8, corresponding to a similar opening in the housing 3 and through which the king-bolt 9 is passed. The broadened Fig. 4 is a detail perspective view of portion 7 of the axletree serves the double function of a reinforcing means around the king-bolt opening 8 and also prevents any longitudinal movement of the axletree relative to the housing 3. The sides of the axletree adjacent to the spindles 4 are also flared outwardly at 6, so as to engage with the sides of the groove 2 to prevent any longitudinal movement. The axletree 1 is held securely within the groove 2 by means of a number of U-bolts 10, which fit around the top of the housing 3 and engage with transverse members 11, extending across the bottom of the axle. Oaps 12 flt upon the ends of the spin. dles 4: to hold the wheels in position and are themselves secured by means of pins 13, passing through corresponding openings in the caps and spindle. Two pins 13 are preferably employed for each cap 12, and the ends of the pins are provided with openings through which strips of leather 14 are passed. These leather strips are removable and serve to prevent the accidental displacement of the pins 13. The hubs of the wheels are preferably provided with axle-boxes 15, provided with an'opening having a corresponding taper to that of the spindles and having ribs 16, which prevent any relative turning of the hub and axle-boxes.

Having thus described the invention, what is claimed as new is The combination of an axletree having a spindle at each end and provided at an in termediate point with an enlarged portion through which a king-bolt-receiving opening is passed, the sides of said axletree flaring outwardly at a point adjacent to the spindles, a housing provided with a longitudinal groove for the reception of the axletree, said groove being enlarged at an intermediate part to receive the enlarged portion of the axletree, and also having its sides flared outwardly at the ends to fit over the flared portions of the axletree adjacent to the spindles, and a king-bolt passing through corresponding openings in the axletree and housing.

In testimony whereof I aflix my signature in presence of two witnesses.
